CORVALLIS — Oregon State wrapped up its second week of spring practice with Friday morning’s workout.

A few observations:

LUKE DEL RIO ELIGIBLE

Luke Del Rio and the Beavers waited longer than anticipated to receive a ruling from the NCAA on the quarterback’s appeal. But the wait was worth it, as Del Rio won the appeal, meaning he’s eligible to play in 2014.

That officially thrusts Del Rio into the backup quarterback derby, where he will compete with sophomore Brent VanderVeen and redshirt freshman Kyle Kempt for the No. 2 spot behind cemented starter Sean Mannion.

Del Rio, who was a three-star prospect and Elite 11 quarterback coming out of high school in 2013, opted to walk on at Alabama before transferring to Oregon State following the season.

Beavers offensive coordinator John Garrett said he had been dividing the practice reps so far this spring with the assumption that Del Rio would be eligible in 2014.

Still, Del Rio acknowledged getting the official news was a big relief.

“I didn’t really see a good reason why I shouldn’t have been (eligible for 2014),” Del Rio said. “So I’m glad that they saw it the same way and I’m excited.”

WHO REPLACES SCOTT CRICHTON?

The biggest void the Beavers must fill in 2014 is clearly the No. 1 receiver spot previously occupied by Biletnikoff winner Brandin Cooks.

But that left defensive end spot is a key opening, too, after Scott Crichton left OSU early to declare for the NFL Draft.

Right now, junior Jaswha James is the frontrunner to take over that job, though redshirt freshman Titus Failagua and senior converted receiver Obum Gwacham are also in the mix.

“Talent-wise, it’s a pretty good group,” coach Mike Riley said. “There’s a mixture of a little bit of age and a major move in Obum and some freshmen that are in it.”

OFFENSIVE LINE BANGED UP

Oregon State’s offensive line is already thin this spring, with starting center Isaac Seumalo and projected starter Josh Mitchell sidelined with injuries. Reserve Will Hopkins also missed practice Wednesday and Friday and had ice on his right foot/ankle during Friday’s workout.

Then, projected starting left tackle Bobby Keenan sustained a right foot injury during team drills. A few plays later, reserve Nolan Hansen hurt his right knee. The extent of either injury was unknown after practice.
